Fremitus? Huh? It irks me when somebody throws out a word or technique but doesn't adequately explain it. You end up going through the motions but don't really understand what you are doing, why you are doing it, and how to tell good from bad (and look kinda silly doing it). Even if it is a skill won't use much (like percussion), why bother to learn if you don't understand? I also hate when teacher bash on Wikipedia, says there's no accuracy. I really believe and would bet my next paycheck that Wikipedia, at least in matters of science, is at least as accurate as any textbook, is updated more than texts, has more editors than any text, and is far easier to use. In this case, a quick search turns up this useful info about fremitus... Tactile fremitusThe reason for increased fremitus in a consolidated lung is the fact that the sound waves are transmitted with less decay in a solid or fluid medium (the consolidation) than in a gaseous medium (aerated lung). Conversely, the reason for decreased fremitus in a pleural effusion or pneumothorax (or any pathology separating the lung tissue itself from the body wall) is that this increased space diminishes or prevents entirely sound transmission.So, got pneumonia? Ninety-nine will feel (or sound) stronger or louder. Got air trapped outside your lungs? Ninety-nine will barely be felt, or not at all.
